The stunning Black Solitaire is almost entirely inky black, aside from a prominent white patch on the side of the head. It is found in wet, mossy montane forests, where it feeds on fruit and berries in small groups or in mixed-species flocks. The behavior is very similar to that of the White-eared Solitaire (Entomodestes leucotis) of Peru and Bolivia, but the Black Solitaire is encountered much less frequently. Due to the restricted range and largely inaccessible habitat, many aspects of its life history are poorly known. Despite its limited range, the Black Solitaire's population is believed to be stable and has not been placed on any threatened species lists. The main threats to the Black Solitaire are habitat disturbance and fragmentation resulting from human activities.
